A hull breach can spawn on top of the ship right where the player normally spawns after climbing the ladder. Fortunately the game just awkwardly has the player stuck on the tile for a bit before shunting them out, so it doesn't really impact gameplay much.
I did have an incident where a hull breach in the ceiling didn't appear from outside my ship, but inside the "air being sucked out" effect still played along with audio cue and I was rapidly losing oxygen. That was annoying, although fixed with a ship upgrade.
